PNV J06302516-6955014: classical nova
I reported the optical spectrum of PNV J06302516-6955014 to ATel and
classified it as a classical nova.
https://www.astronomerstelegram.org/?read=17224
ASAS-SN also detected its rise on 2025-06-04.

TCP J20131357+1154031: new SU UMa-type dwarf nova, possibly WZ Sge-type
K. Itagaki discovered TCP J20131357+1154031 on 2025-05-19 UTC at 14.7 mag
(unfiltered). The outburst amplitude is ~8.4 mag.
https://www.aavso.org/vsx/index.php?view=detail.top&oid=10848625
SAAO/Lesedi telescope, Josch Hambsch, and Sano-san have reported the
time-resolved observations. Josch's observations after 28 May show
single-peaked variation with a period of 0.05797(6) d, likely an ordinary
superhump. No clear …
[View More]modulations were presented before this.
Thus TCP J20131357+1154031 is a new SU UMa-type dwarf nova and a good
candidate for a WZ Sge-type dwarf nova, given its late appearance of
ordinary superhumps.

Yusuke

ASASSN-25ce: new WZ Sge-type dwarf nova
ASAS-SN discovered ASASSN-25ce on 2025-05-28 UTC at 12.26 mag. The Gaia
counterpart is G~20.7 mag thus the outburst amplitude is ~8.5 mag.
The SAAO team and Berto Monard reported the time-resolved observations.
These light curves show a double-peak modulation with an amplitude of ~0.1
mag and a period of ~0.05537(1) d. The 5-sec resolution observations by the
SAAO/Lesedi telescope also show QPO-like modulation with 5--10 min.
Hence, ASASSN-25ce is a new …
[View More]WZ Sge-type dwarf nova, possibly with a
relatively higher inclination, while no clear eclipses are present.
Further time-resolved observations are encouraged.
Best regards,
Yusuke
